618vuotiaat

618vuotiaat (Finnish for six hundred eighteen-year-olds) is a term used in Finnish-language speculative discourse to describe a hypothetical population defined by extreme longevity, potentially reaching or exceeding several centuries, in particular 618 years. It functions as a thought experiment rather than a real demographic category and is most commonly encountered in science fiction writing, futurist essays, and online discussions about longevity and post-human futures.

The expression combines the numeral 618 with the Finnish plural noun vuotiaat, meaning “year-olds.” It carries no fixed scientific definition; accuracy, whether by biology or technology, varies between contexts, and the term is often used rhetorically to frame questions about long life spans.

In hypothetical scenarios, 618vuotiaat would influence almost every aspect of society. Extended lifespans could reshape education, labor markets, pensions, family structure, property, governance, memory and identity, and the ethics of access to life-extension technologies. The term is frequently employed to discuss the social and policy challenges associated with aging populations.

Usage is limited to niche discussions and satire; it is not an established demographic category. Critics argue that the concept can oversimplify complex issues surrounding technology, equity, and societal change.
